TECHNICAL FIELD OF THE INVENTION

The present invention generally relates to a big telematics data device,method and system for application in vehicular telemetry environments.More specifically, the present invention relates to a mobile device realtime big telematics data network communication fault identificationsystem.

BACKGROUND OF THE INVENTION

Vehicular Telemetry systems are known in the prior art where a vehiclemay be equipped with a vehicular telemetry hardware device to monitorand log a range of vehicle parameters. An example of such a device is aGeotab™ GO device. The Geotab GO device interfaces to the vehiclethrough an on-board diagnostics (OBD) port to gain access to the vehiclenetwork and engine control unit. Once interfaced and operational, theGeotab GO device monitors the vehicle bus and creates of log of rawvehicle data. The Geotab GO device may be further enhanced through aGeotab I/O expander to access and monitor other variables, sensors anddevices resulting in a more complex and larger log of raw data.Additionally, the Geotab GO device may further include a GPS capabilityfor tracking and logging raw GPS data. The Geotab GO device may alsoinclude an accelerometer for monitoring and logging raw accelerometerdata. The real time operation of a plurality of Geotab GO devicescreates and communicates multiple complex logs of some or all of thiscombined raw data to a remote site for subsequent analysis.

The data is considered to be big telematics data due to the complexityof the raw data, the velocity of the raw data, the variety of the rawdata, the variability of the raw data and the significant volume of rawdata that is communicated to a remote site on a timely basis. Forexample, on 10 Dec. 2014 there were approximately 250,000 Geotab GOdevices in active operation monitoring, tracking and communicatingmultiple complex logs of raw telematics big data to a Geotab datacenter. The volume of raw telematics big data in a single day exceeded300 million records and more than 40 GB of raw telematics big data.

The past approach for transforming the big telematics raw data into aformat for use with a SQL database and corresponding analytics processwas to delay and copy each full day of big telematics raw data to aseparate database where the big telematics raw data could be processedand decoded into a format that could provide meaningful value in ananalytics process. This past approach is resource consuming and istypically run during the night when the number of active Geotab GOdevices is at a minimum. In this example, the processing and decoding ofthe big telematics raw data required more that 12 hours for each day ofbig telematics raw data. The analytics process and corresponding usefulinformation to fleet managers performing fleet management activities isat least 1.5 days old, negatively influencing any real time sensitivefleet management decisions.

Past approaches to monitoring big time telematics data for networkcommunication faults were previously limited due to the processing anddelays in receipt of data. These data delays and a lack of augmented orsupplemented data also impaired the ability to determine the location ofa network communication fault based upon real time mobile devicecoordinates.

Then, dependent upon thespecific configuration previously described, each vehicle 11 may furtheralso include in a log, at least one of category 2, category 3, category4 and category 5 raw telematics data through the vehicular telemetryhardware system 30.

A number of special purpose servers 19 are also part of the vehiculartelemetry analytical environment and communicate over the network 18.The special purpose servers 19 may be one server, more than one server,distributed, Cloud based or portioned into specific types offunctionality such as a supplemental information server 52, externalthird party servers, a store and forward server 54 and an analyticsserver 56. Computing devices 20 may also communicate with the specialpurpose servers 19 over the network 18.

In an embodiment of the invention, the logs of raw telematics data arecommunicated from a plurality of vehicles in real time and received by aserver 54 with a store and forward capability as raw telematics big data(RTbD). In an embodiment of the invention, an analytical telematics bigdata constructor 55 is disposed with the server 54. The analyticaltelematics big data constructor 55 receives the raw telematics big data(RTbD) either directly or indirectly from the server 54. The analyticaltelematics big data constructor 55 has access to supplemental data (SD)located either directly or indirectly on a supplemental informationserver 52. Alternatively, the supplemental data (SD) may be disposedwith the server 54. The analytical telematics big data constructor 55transforms the raw telematics big data (RTbD) into analytical telematicsbig data (ATbD) for use with a server 56 having big data analyticalcapability 56. An example of such capability is the Google™ BigQuerytechnology. Then, computing devices 20 may access the analyticaltelematics big data (ATbD) in real time to perform fleet managementqueries and reporting. The server 56 with analytic capability may be asingle analytics server or a plurality of analytic servers 56 a, 56 b,and 56 c.

One example of transforming the raw telematics big data (RTbD) intoanalytical telematics big data (ATbD) is for performing queries andreporting concerning a mobile device communication fault with respect toa communications network. The raw telematics big data (RTbD) contains atleast one GPS location of the mobile device and associated vehicle(latitude and longitude information). Supplemental information in theform of supplemental data (SD) may then add a particular location of thevehicle (road or street or address) on a map as illustrated in FIG. 4with respect to the vehicle icons A through K inclusive. In addition,the supplemental data (SD) may also be applied to illustrate differentcommunication zones or communication areas 51 on the map 50. Thispermits a correlation between a vehicle or mobile device location on themap with respect to the communication zone or area 51. Should a mobiledevice have a communication problem, the communication zone or area 51may be identified from an analysis of the big data.

Analytical Telematics Big Data Constructor

Referring now to FIG. 6 a, an embodiment of the analytical telematicsbig data constructor 55 is described. Persons skilled in the artappreciate that the analytical telematics big data constructor 55 may bea stand-alone device with a microprocessor, memory, firmware or softwarewith communications capability. Alternatively, the analytical telematicsbig data constructor 55 may be integral with a special purpose server,for example a store and forward server 54. Alternatively, the analyticaltelematics big data constructor 55 may be associated or integral with avehicle telemetry hardware system 30. Alternatively, the functionalityof the analytical telematics big data constructor 55 may be a Cloudbased resource. Alternatively, there may be one or more analyticaltelematics big data constructors 55 for transforming in real time theraw telematics big data (RTbD) into analytical telematics big data(ATbD).

The analytical telematics big data constructor 55 receives in real timethe raw telematics big data (RTbD) into a data segregator. The rawtelematics big data (RTbD) is a mixed log of raw telematics data andincludes category 1 raw vehicle data and at least one of category 2,category 3, category 4 or category 5 raw telematics data. Personsskilled in the art appreciate there may be more or less than fivecategories of raw telematics data. The data segregator processes eachlog of raw telematics data and identifies or separates the data intopreserve data and alter data in real time. This is performed on acategory-by-category basis, or alternatively, on a sub-category basis.The preserve data is provided in the raw format to a data amalgamator.The alter data is provided to a data amender. The data amender obtainssupplemental data (SD) to supplement and amend the alter data withadditional. information. The supplemental data (SD) may be resident withthe analytical telematics big data constructor 55 or external, forexample located on at least one supplemental information server 52, orlocated on at least one store and forward server 54 or in the Cloud andmay further be distributed. The data amender then provides the alterdata and the supplemental data to the data amalgamator. The dataamalgamator reassembles or formats the preserve data, alter data andsupplemental data (SD) to construct the analytical telematics big data(ATbD) in real time. The analytical telematics big data (ATbD) may thenbe communicated in real time, or streamed in real time, or stored inreal time for subsequent real time fleet management analytics. In anembodiment of the invention, the analytical telematics big data (ATbD)is communicated and streamed in real time to an analytics server 56having access to the Google BigQuery technology.

Referring now to FIG. 6 b, another embodiment of the analyticaltelematics big data constructor 55 is described. In this embodiment, thedata segregator process the raw telematics big data (RTbD) into aplurality of distinct data (1, 2, 3, n) types or groups based upon thecategories. The plurality of preserve data is then provided to the dataamalgamator for assembly with the amended data for assembly into theanalytical telematics big data (ATbD).

Referring now to FIG. 6 c, another embodiment of the analyticaltelematics big data constructor 55 is described. In this embodiment thedata segregator processes the raw telematics big data (RTbD) intopreserve data (category 1) and a plurality of distinct alter data (A, B,C, n) types or groups based upon the categories (2, 3, 4 and 5). Forexample, one category may be engine data that is in a machine format.This machine format may be translated into a human readable format.Another example may be another category of GPS data in a machine formatof latitude and longitude coordinates. This different machine format maybe augmented with human readable information. The alter data types areprovided to the data amender and the data amender obtains a plurality ofcorresponding supplemental data (SD) types (A, B, C, n). The dataamender then amends the alter data types with the correspondingsupplemental data types. The preserve data and the plurality of amendeddata is provided to the data amalgamator for assembly into theanalytical telematics big data (ATbD).

Persons skilled in the art appreciate that there may be one preservedata, one alter data, at least one preserve data, at least one alterdata in different combinations between the data segregator and dataamalgamator.

Analytical Telematics Big Data Constructor and Active Buffers

Another embodiment of the invention including at least one active bufferor blocking queue is described. with reference to FIGS. 7 a, 7 b, and 7c. A first active buffer (see FIG. 7 a ) may be disposed with theanalytical telematics big data constructor 55. The first active buffermay temporally retain at least one alter data. In an embodiment of theinvention, the first active buffer is disposed intermediate the datasegregator and data amalgamator. The first active buffer assists theanalytical telematics big data constructor 55. For example, theprocessing of the raw telematics big data (RTbD) in the data segregatormay be at a more constant rate in contrast to the processing of thealter data and supplemental data in the data amender. When a differencein processing rates occurs, or differences in timing, the first activebuffer may smooth intermittent heavy data loads and minimize any impactof peak demand on availability and responsiveness of the analyticaltelematics big data constructor 55 and external services andsupplemental data acquisition.

Alternatively, a second active double buffer or double blocking queue(see FIG. 7 b ) may also be disposed with the analytical telematics bigdata constructor 55. The second active double buffer may temporallyretain the analytical telematics big data (ATbD). This may occur when acommunication or streaming request fails due to either network issues orexceptions with the analytics server 56. The analytical telematics bigdata (ATbD) is held in the second active double buffer such that thedata is available and communicated successfully to the analytics server56 in a real time order and sequence. In an embodiment of the invention,the second active double buffer is disposed after the data amalgamator.

Alternatively, another embodiment with active buffers is illustrated inFIG. 7 c and includes both the first active buffer and the second activedouble buffer.

Supplemental Data, Translation Data & Augmentation Data

Another set of embodiments of the invention is illustrated with exampleclassifications or groups of supplemental data as shown with referenceto FIGS. 8 a, 8 b and 8 c. The data segregator processes the rawtelematics big data (RTbD) into three types or streams of data. Thefirst type of data is preserve data that is passed directly to the dataamalgamator. A second type of data is alter translate data and the thirdtype of data is the alter augment data. The data amender for thisembodiment may be at least one data amender.

The alter translate data requires translation data. The data amenderobtains supplemental data (SD) in the form of translation data (TD) toamend the alter translate data. The translation data (TD) may beresident with the analytical telematics big data constructor 55 orexternal, for example located on at least one translation server 53.

The alter augment data requires augmentation data (AD). The data amenderobtains supplement data (SD) in the form of augmentation data to amendthe alter augment data. The augmentation data (AD) may be resident withthe analytical telematics big data constructor 55 or external, forexample located on at least one augmentation server 57. The dataamalgamator reassembles or formats the preserve data, amended translatedata and amended augment data to construct the analytical telematics bigdata (ATbD). The analytical telematics bid data (ATbD) may then becommunicated or streamed in real time or stored in real time forsubsequent real time fleet management analytics.

The embodiment in FIG. 8 b is similar to the embodiment in FIG. 8 a, butthe analytical telematics big data constructor 55 only providestranslation data and preserver data in the transformation to analyticaltelematics big data (ATbD). The embodiment in FIG. 8 c is also similarto the embodiment in FIG. 8 a, but the analytical telematics big dataconstructor 55 only provides augmentation and preserve data in thetransformation to analytical telematics big data (ATbD). The alternativeembodiments of FIG. 8 b and FIG. 8 c are examples of analyticaltelematics big data constructors 55 dedicated to particular streams andcategories of raw telematics big data (RTbD). Persons skilled in the artappreciate the analytical telematics big data constructor may processpreserve data, alter data, or a combination of preserve data and alterdata.

Another set of embodiments of the invention includes example categoriesof supplemental data and active buffers. This is described withreference to FIGS. 9 a, 9 b and 9 c. The data segregator processes theraw telematics big data (RTbD) into three types of data. The first typeof data is preserve data that is passed directly to the dataamalgamator. A second type of data is alter translate data and the thirdtype of data is the alter augment data. At least one active buffer isprovided to the analytical telematics big data generator 55 to bufferone of or both of the alter translate data and the alter augment data.The data amender obtains supplemental in the form of translation data(TD) to amend the alter translate data and the supplemental data (SD) inthe form of augmentation data (AD) to amend the alter augment data, Thedata amalgamator reassembles or formats the preserve data, amendedtranslate data and the amended augment data to construct the analyticaltelematics big data (ATbD) that may then be communicated or streamed inreal time or stored in real time for subsequent real time fleetmanagement analytics.

An example is described with respect to GPS data found in the rawtelematics big data (RTbD). GPS data contains a latitude and longitudeindication of a vehicle or mobile device. The GPS data may betransformed into analytical telematics bid data (ATbD) in two ways. TheGPS data may be transformed into a location such as a road, highway,street or address. Then an icon representing the vehicle may beassociated with a moving map 50 to provide a location of the vehicle.The GPS data may also be transformed into a network area or zone or cell51 or multiple areas or zones 51 (see FIG. 4 ). Then the iconrepresenting the vehicle may be also associated with a network area orzone 51 on the moving map 50.

The embodiment in FIG. 9 b is similar to the embodiment in FIG. 9 a, butthe analytical telematics big data constructor 55 only providestranslation data and preserve data in the transformation to analyticaltelematics big data (ATbD). The embodiment in FIG. 9 c is also similarto the embodiment in FIG. 9 a, but the analytical telematics big dataconstructor 55 provides augmentation and preserve data in thetransformation to analytical telematics big data (ATbD). Thesealternative embodiments of FIG. 9 b and FIG. 9 c are also examples ofanalytical telematics big data constructors 55 dedicated to particularstreams and categories of raw telematics big data (RTbD).

The embodiments illustrated in FIGS. 10 a, 10 b and 10 c are similar tothe embodiments in FIGS. 9 a, 9 b and 9 c and further include both thefirst active buffer and second active double buffer. The first activebuffer is disposed in the analytical telematics big data constructor 55intermediate the data segregator and data amalgamator. The second activedouble buffer is disposed after the data amalgamator.

Analytical Telematics Big Data Constructor & Example Data Flow

Table 1 provides an example list of categories of raw telematics data,example data for each category and an indication for any supplementaldata required by each category. Category 1 is illustrated as a pair ofsub-categories 1a and 1b but may also be organized into two separatecategories. Table 1 is an example where the raw telematics data includesdifferent groups or types of similar data in the form of data subsets.

Persons skilled in the art appreciate other categories, orsub-categories of raw telematics big data (RTbD) and other categories orsub-categories of supplement data (SD) may be included and transformedinto analytical telematics big data (ATbD) by the analytical telematicsbig data constructor 55 of the present invention.

State Machine Representation

Referring now to FIGS. 12 a, 12 b, and 12 c, a state machinerepresentation of the logic associated with the analytical bigtelematics constructor 55 is described. There are four states to thelogic that operate concurrently and in parallel. There may further bemultiple instances of each state. The initial state is the datasegregator state. The logic of the data segregator state is to filter,identify and separate the raw telematics big data (RTbD) into preservedata and alter data. The data segregator state waits for receipt of alog or portion of raw telematics big data (RTbD). Upon receipt, the datasegregator processes the raw telematics big data (RTbD) into either atleast one preserve data path or at least one alter data path. The rawtelematics big data (RTbD) in the at least one preserve data path isoptionally provided to a first active buffer or directly to the dataamalgamator state. The raw telematics big data (RTbD) in the alter datapath is optionally provided to a first active buffer or directly to thedata amender state. Then, the data segregator state waits for receipt ofthe next log or portion of raw telematics big data (RTbD).

In an example embodiment of the invention, category 1a and 3 arepreserve data and are provided to the data amalgamator state. Category1b, 2, 4 and 5 are alter data and are provided to the data amenderstate.

The logic of the data amender state is to identify each category ofalter data and associate a category of supplemental data with eachcategory of alter data and provide amended data (alter data andsupplemental data) to the data amalgamator state. The data amender statewaits for receipt of a portion of raw telematics big data (RTbD) that isidentified as alter data. Then, the data amender state obtainssupplemental data for the alter data. This occurs for each category ofalter data and associated supplemental data. Finally, the data amenderstate provides the amended data (each alter and each supplemental data)to the data amalgamator state.

In an embodiment of the invention, the data amender state has twosub-states, the translate data state and the augment data state. Thetranslate data state obtains translate data for particular categories ofalter data that require a translation. The augment data state obtainsaugment data for particular categories of alter data that requireaugmentation. Persons skilled in the art appreciate other sub-states maybe added to the data amender state.

In an example embodiment of the invention Category 2 requires augmentdata and category 1b, 4 and 5 require translate data. Example augmentdata and translate data are previously illustrated in Table 1.

The logic of the data amalgamator state is to assemble, or format, orintegrate the preserve data, alter data and supplemental data into theanalytical telematics big data (ATbD). The data amalgamator statereceives the preserve data from the data segregator and the amended datafrom the data amender state. The preserve data is processed into theformat for the analytical telematics big data (ATbD). The analytical bigtelematics data (ATbD) in the preserve data path is optionally providedto a second active double buffer or directly to the data amalgamatorstate.

The logic of the data transfer state is to communicate or store orstream the analytical big telematics data (ATbD) to an analytics server56 or a Cloud computing based resource. The data transfer state receivesthe analytical big telematics data (ATbD) either directly from the dataamalgamator state or indirectly from the second active double buffer.The analytical big telematics data (ATbD) is then provided to theanalytics server 56 or the Cloud computing based resource.

Process Logic & Tasks

The process logic and tasks of the present invention are described withreference to FIGS. 13 a, 13 b, 13 c, 13 d, 13 e and 13 f. The datasegregator state logic and tasks begins by obtaining in real time a logof raw telematics big data (RTbD). The log of raw telematics big data(RTbD) is segregated into at least one preserve data category and atleast one alter data category. In an embodiment of the invention, thereis than one preserve data category, and no alter category etc. Thepreserve data is made available to the data amalgamator. The at leastone alter data is made available to the data amender. The process logicand tasks may auto scale as required for the log of raw telematics bigdata (RTbD). The data segregator state logic and tasks may be eithersequential processing or parallel processing or a combination ofsequential and parallel processing.

The process logic and tasks for the data amender state logic and tasksbegins by obtaining the at least one alter data from the datasegregator. For each of the at least one alter data, the correspondingsupplemental data is obtained. Each of the at least one alter data isamended with the corresponding supplemental data to form at least oneamended data. The at least one amended data is made available to thedata amender. The process logic and tasks may auto scale as required foreither the alter data and/or the supplemental data.

The process logic and tasks for the data amalgamator state logic andtasks begins by obtaining the at least one preserve data from the datasegregator and the at least one amended data from the data amender. Theat least one preserve data and the at least one amended data isamalgamated to form the analytical telematics big data. The processlogic and tasks may auto scale as required either for the at least onepreserve data and/or the at least one amended data. The data amalgamatorstate logic and tasks may be either sequential processing or parallelprocessing or a combination of sequential and parallel processing.

The process logic and tasks for the data transfer state logic and tasksbegins by obtaining the analytical telematics big data (ATbD) from thedata amalgamator. The analytical telematics big data (ATbD) iscommunicated or streamed to an analytical server or Cloud basedresource. The process logic and tasks may auto scale as required for theanalytical telematics big data (ATbD).

Load Balancing

Another broad feature of the present invention is described withreference to FIGS. 3, 6 b, 7 c, 12 b, 13 a, 13 b, 13 c, 13 d, 13 e and13 f. As illustrated on the map 50, many different vehicles 11 can beoperational at any given time throughout the world in many differenttime zones all monitoring, logging and communicating raw telematics datato a analytical telematics big data constructor 55 in real time. Thecategories and type of raw telematics data (see Table 1) may also varygreatly dependent upon the specific configurations of each vehicle 11(vehicular telemetry hardware system 30, intelligent I/O expanders 50,devices 60, Bluetooth modules 45 and Bluetooth Beacons 21 associatedwith a plurality of objects). This results in a unique big datavelocity, timing, variety and amount of raw telematics data thatcollectively forms the raw telematics big data (RTbD) entering the datasegregator of the analytical telematics big data constructor 55. This iscollectively referred to as a raw telematics big data (RTbD) load.

There are also many different types of supplemental data (SD) requiredby the data amender available from many different locations and remotesources. The supplemental data (SD) is also dependent upon the portionor mix of raw telematics big data (RTbD). This results in another uniquebig data velocity, timing, variety and amount of supplemental data (SD)(see Table 1 augment data and translate data) required by the dataamender. This is collectively referred to as a supplemental data load.

Communicating or streaming the analytical telematics big data (ATbD) toan analytics server 56 or a Cloud based resource is also dependent uponthe analytics server 56 or Cloud based resources ability to receive theanalytical telematics big data (ATbD). This results in another big dataunique velocity, timing, variety and availability Lo communicate orstream the analytical telematics big data (ATbD). This is collectivelyreferred to as an analytical telematics big data (ATbD) load.

The end result is a plurality of potential imbalances for the load,velocity, timing variety and amount of raw telematics big data (RTbD),supplemental data (SD) and analytical telematics big data (ATbD).Therefore, the analytical telematics big data constructor 55, finitestate machine, process and tasks of the present invention must be ableto deal in real time with this imbalance in real time.

In an embodiment of the invention, this imbalance is resolved by theunique arrangement of the pipelines, filters and tasks associated withthe analytical telematics big data constructor 55. This uniquearrangement permits load balancing and scaling when imbalances occur inthe system. For example, the pipelines, filters and tasks may bedynamically increased or decreased (concurrent instances) based upon thereal time load. The data is standardized into specific formats for eachof the finite states, logic, resources, processes and tasks. Thisincludes the raw telematics big data (RTbD) format, the supplementaldata (SD) format, the preserve data format, the alter data format, theaugment data (AD) format, translation data (TD) format and theanalytical telematics big data (ATbD) format. In addition, a uniquepipeline structure is provided for the analytical telematics bid dataconstructor 55 to balance the load in the system. The raw telematics bigdata enters the analytical telematics big data constructor through afirst pipeline to the data segregator. The data segregator then passesdata through at least two pipelines as preserve data and alter data. Thealter data pipeline may further include additional pipelines (A, B, C,n). The alter data pipelines feed into the data amender with thecorresponding supplemental data (SD) pipelines. The amended datapipelines and the preserve data feed into the data amalgamator andfinally, the analytical telematics bid data (ATbD) feeds into thecommunication or streaming pipeline. This architecture of telematicsspecific pipelines permits running parallel and multiple instances ofthe data segregator state, the data amender state, the data amalgamatorstate and the data streaming state enabling the system to spread theload and improve the throughput of the analytical telematics bid dataconstructor 55. This also assists with balancing the system insituations where the data, for example raw telematics bid data (RTbD)and the supplemental data (SD) are not in the same geographicallocation.

In another embodiment of the invention, this imbalance is resolved bythe application of the first active buffer and/or the second activebuffer either alone or in combination. The first active buffer handlesthe imbalance between the raw telematics big data (RTbD) and thesupplemental data (SD). The second active buffer handles the potentialimbalance when communicating or streaming the analytical telematics bigdata (ATbD) to an analytics server 56 or a Cloud based resource. Thebuffers may scale up or down dependent upon the needs of the analyticaltelematics big data constructor 55.

In another embodiment of the invention, this imbalance is resolved bythe layout of the finite state machine, the logic, the resources, theprocess and the tasks of the process through a unique and specifictelematics computing resource consolidation.

The data segregator state, logic, process and tasks automatically dealwith scalability of the raw telematics big data (RTbD) and associatedprocessing tasks to filter the data into preserve data and alter data.This includes both scaling up or down dependent upon the correspondingload required by the raw telematics big data (RTbD) and the amount ofprocessing required to segregate portions of the data into preserve dataor alter data. Additional instances of the data segregator state, logic,process and tasks may be automatically started or stopped according tothe load, demand or communication requirements.

The data amender state, logic, process and tasks automatically deal withthe scalability with the supplemental data (SD). This includes bothscaling up or down dependent upon the corresponding load required by thesupplement data (SD) and the amount of processing required to amend eachalter data. Additional instances of the data amender state, logic,process and tasks may be automatically started or stopped according tothe load, demand or communication requirements.

The data amalgamator state, logic process and tasks automatically dealwith the scalability with the preserve data, amended data and ability tocommunicate or stream the analytical telematics big data (ATbD) to ananalytics server 56 or Cloud based computing resource. Additionalinstances of the data amalgamator state, logic, process and tasks may beautomatically started or stopped according to the load, demand orcommunication requirements.

The analytical telematics big data constructor 55 enables real timeinsight based upon the real time analytical telematics big data. Forexample, the data may be applied to monitor the number of Geotab GOdevices currently connecting to the special purpose server 19 andcompare that to the number of GO devices that is expected to beconnected at any given time during the day; or be able to use the realtime analytical telematics big data to monitor the GO devices that areconnecting to their special purpose server 19 from each cellular orsatellite network provider. Using this data, managers are able todetermine if a particular network carrier is having issues for proactivenotification with customers that may be affected by the carrier'soutage.

Real Time Network Communication Fault Determination

The big telematics data communication fault monitoring system is nextdescribed with respect to FIG. 4 and FIG. 11 . Each mobile devicecommunicates to the remove device in the form of raw telematics big data(RTbD). This data includes GPS data that is identified for amendment.The amendment includes augmentation data in the form of postal codes, orZIP codes, or street address, or names of contacts or addresses topermit associating a vehicle location on a map 50. The amendment alsoincludes augmentation data in the form of network areas or network zonesor networks cells 51 to permit associating a vehicle location within acommunication network and the overlay of the area or zone or cell 51 ona map 50. In an embodiment of the invention, the augmentation data is acell identification number used to identify a base transceiver stationor sector of a base transceiver station within a location area code. Thecell identification number pertains to GSM, CDMA, UMTS, LTE, WiFi andother forms of communication networks. In addition, the augmentationdata may further include mobile network codes and the identificationnumber of the carrier or operator. The identification numbers areavailable from a number of different databases and service providers

As illustrated in FIG. 4 , the map 50 illustrates a number of iconsrepresentative of vehicles (A through K) moving in real time. There arethree network zones or areas 51 also overlaid on the map 50. In onecommunication zone or area 51, there is vehicle D. In anothercommunication zone or area 51, there are vehicles A, B, C, E, and H. Inanother communication zone or area 51 there are vehicles I, J, and K.And finally, vehicles F and G are not associated with a communicationzone or area 51.

If a mobile device associated with vehicle D were to ceasecommunication, it may be a communication fault with the mobile deviceassociated with vehicle D or it may be a fault with the communicationnetwork. If mobile devices associated vehicles A, B, C, E and H ceasecommunication, the most likely fault is with respect to thecommunication network zone or area associated with these vehicles.Likewise, if mobile devices associated with vehicles I, J, and K were tocease communication, the most likely fault is with respect to thecommunication network zone or area associated with these vehicles.However, if mobile devices associated with vehicles F and G were tocease communication, this would be expected as the vehicles are notlonger associated within a communication zone or area.

Referring now to FIG. 14 a, a state representation for determining acommunication fault based upon expected communication and actualcommunication is next described. There are two primary states, theremote device communication fault determination state and the mobiledevice expected communication mode state. The mobile device expectedcommunication mode state includes an active mode sub-state and aninactive mode sub-state. The inactive mode state, representative oftiered power saving modes for the mobile device further include twosub-states, a sleep state and a deep sleep state.

The remote device communication fault determination state and the mobiledevice expected communication mode state are asynchronous and may beconcurrent or non-concurrent. The remote device communication faultdetermination state provides a determination of a potentialcommunication fault by comparing the total number of expectedcommunications from a plurality of mobile devices with the actual numberof communications in a particular time frame sample.

The active mode occurs when a mobile device is fully powered up andoperational. The active mode provides a first periodic frequency ofcommunication, or a first expected communication for the remote device.In an embodiment of the invention, the first frequency of communicationis every 100 seconds and persons skilled in the art will appreciate thatthe first frequency of communication may include other different values.

The inactive mode occurs when a mobile device is powered down into atleast one power saving mode. The sleep sub-state or mode is a firstpower saving mode and it provides a second periodic frequency ofcommunication, or second expected communication for the remote device.In an embodiment of the invention, the second frequency of communicationis every 30 minutes, or 1800 seconds and persons skilled in the art willalso appreciate that the second frequency of communication may includeother different values. The deep sleep sub-state or mode is a secondpower saving mode and it provides a third periodic frequency ofcommunication, or third expected communication for the remote device. Inan embodiment of the invention, the second frequency of communication isevery 24 hours, or 86,400 seconds and persons skilled in the art willalso appreciate that the third frequency of communication may includeother different values.

The three frequency of communications provide three known expectedcommunication time frames, or thresholds for the remote device. Theexpected communication could be in the form of a signal, data, and/or amessage dependent upon the mobile device. For example, if the mobiledevice is ready to communicate a log of data, the communication could bein the form of data. If the mobile device is not ready to communicate alog of data, the communication could be in the form of a message with adevice id.

The remote device communication fault determination logic tracks andsums the expected connections based upon the mobile device expectedcommunication mode states and as illustrated in Table 2 may include aplurality of mobile devices operating with the first frequency ofcommunication, or a plurality of mobile devices operating with thesecond frequency of communication, or a plurality of mobile devicesoperating with the third frequency of communication as well ascombinations of the first, second and third frequencies ofcommunication.

Referring now to FIG. 14 b, the data preprocessing for determining acommunication fault based upon expected communication and a period ofactual communication is described. Different types and categories ofdata are preprocessed in real time to create the analytical telematicsbig data (ATbD) used for determining a network communication fault. Thepreprocessing may be with a special purpose server 19, or anothercomputing device 20. The GO device data log (RTbD) is historical dataover a period of time and includes at least one GPS data and anindication of the vehicle status. The supplemental data (SD) includeslocation data and network data. The GO device data log (RTbD) iscombined with the supplemental data (SD) to form the analytical data(ATbD). The supplemental data may be sourced internally with the systemor externally to the system. In an embodiment of the invention the, theGPS data is in the form of latitude and longitude coordinates, includinga time indication, and the vehicle status data is an engine on or offindication or another indication representative of an active mode andinactive mode for the mobile device. In an embodiment of the invention,the location data may include at least one of a postal code, a ZIP code,a street address, a road indication, a highway indication, a name,contact information or a phone number. In an embodiment of theinvention, the network data may include at least one of a serviceprovider name, a network area, a network zone or a network cellindication.

The preprocessing of data may include an auto scale capability tobalance the real time streaming of the data. In embodiments of theinvention, the auto scale capability may be a buffer, a double buffer ora combination of a buffer and double buffer.

Referring now to FIG. 15 , the mobile device expected communicationperiod determination logic is described. The mobile device detects thevehicle status. In an embodiment of the invention, the detection occursbetween the interface 36 of the vehicular telemetry hardware system 30and the vehicle network communications bus 37. After the vehicle statushas been detected, the vehicle status is checked to determine if thestatus is true or false. In an embodiment of the invention, the vehiclestatus is a code for “ignition on” and if the status is “on”, the checkis true or if the status is “off”, the check is false. If the check istrue, then the active mode is set to indicate a first communicationperiod.

If the check is false, then the inactive mode is set. For the casewherein there are a plurality of power saving modes, a subsequent checkis made with respect to an inactive period threshold. If the thresholdhas not been reached (indicative of a first power saving mode), then asecond communication period is set. If the threshold has been reached(indicative of a second power saving mode), then a third communicationperiod is set.

Once the first or second or third communication periods have been set orre-set between the periods based upon the logic, the mobile devicecommunicates with a remote device based upon one of the communicationperiods as an expected communication. The vehicle status is checked todetermine if the vehicle status has changed. Then, the mobile deviceexpected communication period determination logic is executed in eachmobile device. In an embodiment of the invention, the mobile deviceexpected communication period determination logic is also a firstasynchronous process.

Referring now to FIG. 16 a, the remote device active/inactivedetermination logic for each mobile device is next described. The remotedevice establishes a sample time frame or timing to check and determinethe presence of one or more communication faults. Then, the remotedevice receives mobile device logs of data from each of the remotedevices within the sample time frame. For each device log of data, theprevious log is decoded to identify the vehicle status indicator fromthe log. If the vehicle status is true, then the remote devicedetermines the mobile device is in an active mode. If the vehicle statusis false, then the remote device determines the mobile device is in aninactive mode. The remote device may then track each mobile device andthe corresponding state of active or inactive.

Referring now to FIG. 16 b, the remote device expected communicationdetermination logic for each mobile device is described. The remotedevice receives a plurality of mobile device logs of data within thecommunication time frame sample. For each log of data, the vehiclestatus is determined. If the vehicle status is true, then the mobiledevice is in an active mode with an expected communication of a firstfrequency period. If the vehicle status if false, then the inactiveperiod threshold is checked. If the threshold has not been reached, thenthe mobile device is in an inactive mode with an expected communicationof a second frequency period. If the threshold has been reached, thenthe mobile device is in an inactive mode with an expected communicationof a third frequency period. The remote device tracks each mobile devicemode, expected communication and frequency period for use and comparisonwith receipt of the next set of mobile device logs in the nextcommunication time frame sample for comparison with the next number ofactual communications from the mobile devices.

In an embodiment of the invention, the remote device active/inactivedetermination logic for each mobile device and the remote deviceexpected communication period determination logic are also a secondasynchronous concurrent process.

Referring now to FIG. 16 c, the remote device expected and actualcommunication fault determination logic is described. When thecommunication time frame sample period has been reached, determine thetotal number of expected connections. The total number of expectedconnections is the sum of the number of mobile devices in an active modewith an expected connection of a first frequency period plus the numberof mobile devices in an inactive mode with an expected connection of asecond frequency period. Alternatively, the total number of expectedconnections may also include the number of devices in an inactive modewith an expected connection of a third frequency period.

A comparison is made with respect to the total number of actualconnections with the number of mobile devices that actually connected.When the total number of expected connections is equal to the totalnumber of actual connections, there is no fault with the communications.When the total number of expected connections is not equal to the totalnumber of actual connections, there is a fault with the communications.When there is a fault with the communications, for each mobile devicethat did not connect, access the augmented GPS coordinates from the dataand compare with the coordinates with a network zone, or area or cell todetermine the location of the fault in the network.

Referring now to FIG. 17 , the remote device network communication faultdetermination logic is described. For each communication faultdetermination associated with a mobile device, determine the augmentedGPS coordinates from the data for the mobile device that was expected tocommunicate and did not communicate. Determine the network area or zoneor cell based upon the augmented GPS coordinates from the data.Alternatively, determine the network area or zone or cell based upon theGPS coordinates from the log of data and supplemental data or augmenteddata. Correlate the mobile device location based upon the GPScoordinates with the network area or zone or cell based upon the GPScoordinates of the mobile device or alternatively the GPS coordinatesand the supplemental data or augmented data. Provide a fault indicationin relationship to each mobile device that did not communicate and thenetwork area or zone or cell. Repeat for each mobile device that did notcommunicate when expected to communicate.

The fault indication may be in the form of a graphic indication on themap 50 identifying the mobile device(s) and the associated network areaor zone or cell. Alternatively, the fault indication may be a textualmessage or an audio message indicating the fault and associated networkarea or zone or cell or report.
